FISHEKIES OF ALASKA IN 1910. 



to a pulp. In two ponds containing about 10,000,000 fry, from 30 to 40 pounds of this 

 food was fed each day, and they appeared to thrive wonderfully well upon it, as 

 scarcely any dead fry were found. 



The rainfall was 160.80 inches and the snowfall 289 inches for the 

 year ended June 30, 1910, at Fortmann hatchery; which record will 

 give a slight idea of the weather conditions with which the super- 

 intendents of hatcheries in Alaska have to contend. Despite the 

 adverse weather conditions, however, all of the hatcheries except 

 Fortmann and Afognak operated at full capacity, and taken as a 

 whole the season was a fairly successful one. 



The Klawak Lake hatchery of the North Pacific Trading & Packing 

 Co. was enlarged the present summer so that it is now able to handle 

 10,000,000 eggs. 



At the dam on the stream leading to Capt. John C. Callbreath's 

 hatchery on McHenry Inlet a man has been stationed each year since 

 the hatchery was shut down, for the purpose of lifting the salmon over 

 the structure. In 1908, 1,022 males and 876 females were put over, 

 and in 1909, 516 males and 434 females.

STATISTICS. 



catch in 1907, 1908, 1909, and 1910. 



Following is a table showing, for the geographic sections, by appara- 

 tus and species and by species alone, the number of salmon caught in 

 the years 1907, 1908, 1909, and 1910. All species, except red salmon, 

 show increases over 1909. The total catch in 1910 is smaller than in 

 any of the other years shown.
